Definitions
- This invention relates to ring binders which hold paper and the like for loose-leaf binders, files, folders and the like.
- Carrier rails in prior art ring binders have the tendency, firstly to be bent when a ring member is attached thereto during assembly, and secondly to twist excessively along the longitudinal axis of the rail when the ring binder is opened and closed.
- US Patent No. 3,246,652 discloses a snap-ring binder having a strip mounted with a number of ring fingers.
- the strip is made of a flexible material and is disposed in a channel.
- the strip is also provided with a number of projections engageable with the sides of the channel. As the strip is wider than the channel, it may be caused to either bow or arc about the said projections, by acting upon a pair of tabs of a stiffening rib, to thereby open or close the ring fingers.
- GB-A-2 209 500 discloses a ring binder mechanism for a loose-leaf binder with ring elements secured to carrier rails within a cover rail.
- the cover rail is provided with a longitudinal indentation which provides increased strength and rigidity to the mechanism.
- a ring binder comprising a housing member, a pair of carrier rails and a plurality of ring members, the housing member supporting the pair of carrier rails which are pivotally mounted relative to each other, each of the ring members being supported by the carrier rails and extending through the housing member, wherein at least one of the carrier rails is provided with at least one longitudinal rib.
- Such an arrangement is particularly useful, since the provision of ribs prevents any excessive bending occurring when ring members are attached to the rail during assembly, and secondly prevents any or excessive twisting movement along the longitudinal axis of the rail occurring when the ring binder is actually being opened and closed, thereby allowing for easier closing and opening of the ring members, since the ring binder is more integral.
- Holes may be provided in the rail in order to act as guiding means for the rail during actual assembly of the ring binder, and the provision of such holes in the rail makes the twisting effect worse.
- the provision of the longitudinal ribs on the rail overcomes this additional twisting problem as well.
- a plurality of ribs are provided along the longitudinal axis of the rail.
- these ribs can be the same length or different lengths.
- the rib has a base parallel to the rest of the rail, at least one side sloped relative to the rest of rail in the longitudinal direction, and one side sloped relative to the rest of the rail in the transverse direction.
- a rib has the advantage that the centre length and width of the rail are effectively made longer and wider due to the indented ribs when compared to a completely flat rail, and accordingly the rail has greater stiffness.
- a ring binder 10 for a loose-leaf binder comprising a base member 12, three ring members 14 spaced along the base member (only one of which is shown in Figure 1), and an opening and closing mechanism 20 at each end of the base member (again only one of which is shown in Figure 1).
- the base member 12 comprises a housing member in the form of an upper rigid structure 24 which is curved in cross-section and which supports between its two overlapping sides 26 a pivotable lower structure 30 comprising two carrier rails 32 pivotable to each other along the longitudinal axis of the binder 10.
- the ring members 14 are mounted on the pivotable lower structure 30 and in particular, one of the ring components (ie component 14a) of each ring member is mounted on the carrier rail 32 while the other ring component (not shown) of each ring member is mounted on the other carrier rail (also not shown).
- Fastening means 34 are also provided on the upper structure 24 in order to secure the ring binder 10 to a paper folder or the like.
- the two carrier rails 32 are movable (ie pivoted about lugs 35) relative to each other between a lower position and an upper position due to the action of the opening and closing mechanism 20 on each end of the carrier rails.
- the opening and closing mechanism 20 is pivotably supported on each end of the upper rigid structure 24 and is in engagement with each end of the pivotable lower structure 30 in order to position the opening and closing mechanism 20 between the upper and lower structures.
- the carrier rail 32 is shown in greater detail in Figure 2, and in particular is shown having a number of longitudinal ribs 36 of varying lengths and each of trough like shape.
- the ribs 36 are deformed and/or pressed relative the rest of the rail 32 such that extra stiffness is provided to the rail.
- the base of the ribs 36 is deformed and/or pressed such that it is parallel to the rest of the rail 32.
- the ribs 36 are also provided with two sides 42 which are sloped relative to the rest of the rail in the longitudinal direction, and two sides 44 which are sloped relative to the rest of the rail in the transverse direction.
- Such a rib provides the advantage that it prevents bending of the rail when the ring member 14a is attached to a corresponding hole 38 provided in the rail during assembly of the ring binder, and also prevents twisting of the rail 32 during opening and closing of the ring members 14 when the ring binder is in actual use.
- An particular advantage of providing the ribs is by increasing the stiffness of the rail, the thickness of the rail can be minimised thereby saving material.
- the thickness of each rail can be lowered by 0.1 mm.
